IMPROVEMENT IN GAS-HEATERS R BLOW-PIPES FOR HEATING SOLDERING-IRONS.

Specification forming part of Letters Patent No. 46,527, dated February2l, 1865.

To all whom it may concern Be it known that I, ErwrN A. LELAND, of thecity, and county, and State of New York, have invented a certain new anduseful article of manufacture, consisting of a Gas-Furnace or Blow-Pipefor Heating Soldering-Tools 5 and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the annexed drawing, making part of this specification, in which isrepresented a vertical longitudinal section through said article ofmanufacture.

The object of my invention is to furnish plumbers, tinners, and othersheet-metal workers with a cheap portable heating apparatus, whichobject I accomplish by making a bent hollow cone (shown by A B) with itsbase elevated a short distance fromv the ground by means of feet or legsin the manner shown, and by introducing in the horn of the cone aperforated tube, c, the lower end whereof is supported by the tube orpipe D, which passes. through the side of the cone and is secured at b.The upper end of the perforated tube should make a tight joint with theend of the cone, and the pipe D should be sufficiently well secured tosupport the lower Now, if gas be introduced into the base of the conethrough a burner or pipe, E, it will issue through the perforated tubeout of the upper end of the cone, where it may be ignited, and where thecombustion will be supported and forced by a draft of air through theblow-pipe D, developing great intensity of heat at the end of the hornand in the tube o around the solderingtool H. On the under side of thehorn of the cone a bracket, G, is made to receive a support, F, toreceive the handle of the soldering-tool.

The tube c and pipe D may be secured as shown in the drawing, or thepipe o may be made thick enough to screw in the end ofthe cone, or theymay be secured by means of ring-nuts and supported by brackets made inthe inside of the cone, and the pipe D, instead of passing through theside or elbow of the cone, may be curved, as shown by the red lines, andbrought down to near the base of the cone, the gas being introduced oneither side of it. The drawing shows the gas introduced through aburner, E, but the burner is unnecessary. An open pipe will answer thesame, if not a better, purpose.

The base of the furnace or cone is raised from the floor to admit thegaspipe and air to the outside of the tubes C and D, but the same objectmay be obtained by cutting holes in the cone around its base, throughwhich thegas-pipe and air can be introduced in substantially the samemanner.

By making the base of the furnace large enough and dividing it withpartitions, and inserting'a horn in each compartment, it may be doubledor even quadrupled, but the same general principles would still beinvolved, and the apparatus would fall within the scope of my invention5 for I do not intend to confine my claim to the particular constructionherein described, but intend it to extend to and cover all the novelfeatures going to make up the whole invention.

Having now described my apparatus, the manner of making and using it,what I claim as my invention, and desire to secure by Letters Patent,is-

The new article of manufacture, consisting of a gas-furnace orblow-pipe, constructed substantially in the manner described, for thepurpose of heating soldering-tools and for other similar purposes.
